Radiant Tube heating offers improved performance and helps to future-proof your business against rising energy costs, by improving energy efficiency across the board.

This field is for validation purposes and should be left unchanged.

What is Radiant Heating?

Radiant tube heating is a more localised and focused form of heating compared to traditional forced-air systems. Radiant tube heating is often used in industrial settings, warehouses, and commercial spaces where a consistent and even heat distribution is desired. The method can be energy-efficient and provides a comfortable warmth without the circulation of air.

Our team has over 25 years of experience designing, planning and installing radiant tube heating in a number of sectors across the UK. With payment options to make your space energy efficient in no time. No matter the heating problem, OKEL has the solution.

Benefits of a Radiant Heating System

Radiant Tube heaters offer low-intensity heat and exceptional energy efficiency. They are often mounted overhead, ideal for buildings with lower ceilings, and unlike other forms of heating Radiant far infrared heat transports through the air without heating it. It heats only the people, machinery, or objects it encounters, therefore removing unnecessary costs associated with heating unoccupied space.

The precision at which they heat makes Radiant Tubes the perfect heat solution for companies looking to spot heat in certain areas, premises with high levels of air changes or those prone to large amounts of heat loss caused by roller shutter doors.

  • Linear
  • U-tube
  • Herringbone

Ranging from 10kW to 100kW capacity to suit all size premises.

Alternatives to Radiant Tubes

If you have a large open space to heat, but find radiant heating isn’t suited to your needs, you may need to investigate alternative heating solutions. Speak to one of our experts today or read more about the heating solutions we provide, based on your individual needs.

Warm Air Heating

Warm Air Heating combined with an effective destratification system can work well for large open-plan premises with high ceilings exceeding 6m.

Boiler Installations

Commercial Boiler Installations can solve heating and hot water problems for buildings more suited to a traditional central heating system, such as care homes, schools, and office space.

Discover the Perfect Radiant Heating Solution for you



Radiant tube heating utilises radiant energy to warm spaces. In this setup, tubes are positioned in the targeted area, housing a heating element such as a gas flame or electric coil. The heating element warms the tubes, which then emit infrared radiation, effectively heating objects and surfaces, including people in the room.

This approach offers a more concentrated and targeted heating solution compared to conventional forced-air systems. Commonly applied in industrial, warehouse, and commercial settings, radiant tube heating ensures a uniform and consistent distribution of warmth. Its energy efficiency and ability to provide comfortable heat without air circulation make it a favoured method in various applications.

Radiant tube heaters can result in energy savings because they minimise heat loss associated with air movement and duct losses. Additionally, since they heat specific areas or objects, users can often achieve comfortable temperatures with lower overall energy consumption.

The actual efficiency can depend on factors such as the insulation of the space, the type of heating element used and the specific design of the radiant tube heating system. Regular maintenance and proper installation are crucial for optimising energy efficiency.

Whether radiant tube heaters are worth it depends on various factors, including your specific heating needs, the characteristics of the space and your personal preferences. Some things to consider are preference for energy efficiency, cost of installation and upkeep, comfort of your staff and visitors, and maintenance requirements. Local climate can also come into play, if you’re based in a colder environment, Radiant Heating can take longer to heat the target areas.

In summary, if energy efficiency, comfort, and tailored heating are important to you, and you’re willing to invest upfront, radiant tube heaters could be worth it. However, it’s advisable to consult with us to assess your specific situation and determine the most suitable heating solution.

Determining the size of the Radiant Tube Heaters you’ll need involves considering several factors related to the space you want to heat.

Firstly, calculate the square footage of the area you want to heat. This is a fundamental factor in determining the heating capacity required. The height of the ceiling is crucial. Higher ceilings may require more powerful radiant tube heaters to ensure effective heating.

Consider the insulation of the space. Well-insulated areas retain heat better, so you may need a smaller heating capacity compared to poorly insulated spaces. As mentioned before, the climate of your location also influences the heating requirements as colder climates may necessitate a higher heating capacity.

The intended use of the space matters. For example, industrial spaces with equipment that generates heat may require less heating capacity than a space where people need to maintain a comfortable temperature. Different types of radiant tube heaters have varying heating capacities too. Once all of these aspects are considered, you’ll have a better understanding of the amount and type of radiant tube heaters you need. As part of our service, we offer a Free Site Audit which will assess all of these aspects and provide you with the data you need to make an informed decision on your heating solution.
